Display Comparison

Both phones feature stunning 6.5-inch OLED displays with a 120Hz refresh rate and 4K resolution. The Pro-I boasts a slightly higher peak brightness of 644 nits compared to the 1 III's 620 nits, but the difference is minimal in real-world usage. Both offer excellent color accuracy and contrast, with the 1 III's 'Cinematic' display mode providing a wider aspect ratio for immersive viewing. The Pro-I's display also benefits from a more refined calibration for professional workflows.

Camera Comparison

This is where the Pro-I truly shines. Its headline feature is a 1-inch Exmor RS sensor, significantly larger than the 1 III's sensor. This translates to superior low-light performance, better dynamic range, and shallower depth of field. The Pro-I also offers more manual controls and professional video recording capabilities. The 1 III still has a very capable camera system with its variable telephoto lens, but it doesn't match the Pro-I's image quality.

Performance

Under the hood, both devices share the same Qualcomm Snapdragon 888 5G chipset and 12GB of RAM, ensuring smooth and responsive performance for demanding tasks and gaming. While the Snapdragon 888 is a generation older, it remains a powerful performer. Differences in real-world performance are likely negligible, with software optimization playing a larger role.

Battery Life

Both phones offer an endurance rating of 87 hours, indicating excellent battery life. While the Pro-I technically has a slightly higher rating, real-world usage will likely be similar. Both support 30W wired charging and wireless charging, with reverse wireless charging capabilities.

Buying Guide

The Sony Xperia 1 III is ideal for users who want a premium smartphone experience with a fantastic display, solid performance, and a capable camera system at a more accessible price point. The Xperia Pro-I is targeted towards professional photographers and videographers who demand the absolute best image quality and advanced features, justifying its higher cost.
